TO ALL WHOM IT MAY CONCERN; 4

Be itvknown that I, WILLIAM J'. MARTIN, of Catawissa, in the county 'ofColumbia, vand State of Pennsylvania, have invented certainvnew anduseful Improvements in Attachments foi` Ploughs and I do hereby declarethat vthe following is a full, clear, and exact description of the same,referencebeing had to the accompanying drawings, making a portionof thisspecification, in which; l

Figure' is a sideview of` aplough fitted with anV attachment madeaccording to luy-invention.

Figure'2is a plan view of the-same.

Similarlettersot` reference indicate corresponding par-ts in bothfigures.

In ploughing ground covered with a growth of tall weeds, cornstalks, 4orother like' vegetation, much diiculty is enperiencedin turning suchvegetation completely over, and covering the saine' with the furrow.'The` object of thisl invention. iste provide an effective means ofobviatin'g this diiculty, and it consists in a sweep or bar, attachedvtothe beam, andai-ranged in such relation with the mould-board of theplough that when the plong'his in' use, the said'bar will bend or throurthe weeds,` Ste., away from the `mould-bcard, and bring them toward theground in such manner-'as to prevent them from interfering with theoperationof the mouldlboard f in inverting the furrow. .t I l Theinvention further consists in a novel means of adjusting theaforesaidibar, whereby it may be readily secured vinsuch position as toinsure its most ecient operation lunderdiiierent circumstances of depthof fu i'` row, or'average height of weeds or vegetation. l l

Theinvention further consists in a novel means, whereby the wrenching ofthe bar or sweep from its fastenings is 4provided against. y l l VToenable others to understand the nature and constructionl of myinvention, I will proceed to describe it with reference to the drawings.I

, The invention is designed `to be applied to plouglis of any suitableconstruction,' A` indicatingthe beamand B the,mould-board o f suchplough. C represents a sweep or bar, made, preferably, ofiwrought iron,and attached, as hereinafter presently explained, to the beam, B, thebar being'}') laccdv in a position nearly parallel withljtlie face ofthe mouldboard, and at an angle to that of the beam, as more fullyindicated ,in iig. 2Q TheV outermost end of the bar being placed at adistance from the face of the mould-board, n otezceeding the height fromlthe bottom ofthe furrow of the yvegetation to be turned under, the barC should be curved downward, as shown more clearly at a, in 1, and itsopposite or inner extremity is designed to exten d inward, lsomewhatbeyond the'point a of the share The bar C is secured to the beam A bymeans of twojlinks, c et, the link o` being provided withan arm orshank, c', pivoted to the inner end of the said bar by a Vtransversepivot, as shown at c",'and the linkd being pivoted to or ,connected withthe b'ar at a point' at the opposite sideofthezbeam. The two linksextend upward, one uponeach side of the beam, and are firmly clampedthereto by the head, (1*, andnut, 6*, respectively, ofaltightening-bolt, the bar being thus rigidly aftixedto thebeam. Byraising or vlowering the two links ed, the bar may be adjusted at agreater or less height from 'thegroluni according as the vegetation tobeturned or ploughed -under is higher or lower. I By moving the lower`portions of the links towardor from the mouldfboard, the barmay beadjusted at any required ldistance therefrom, and by varying thepositionof the said links with reference to each other, .the bar maybebrought to any required angle to the face of the mould-board or to thebeam.- Extended from the forward end of the beam :A ,I'to any desiredpoint ofthe outermost portion of the b ar G, is achain, D, which servesas a brace to sustain thefbar C against the rearward strain exertedthereon by the weeds, cornstalks, 5to., which are pressed forwardand-downward bythe actionof thesaid bar, as presently hereinexplained. y4

As the plough is drawn along in the operation o t ploughingthe sweeperbar Q 'strilies the cornstalks, `vs'eeds, or other rank or tallvegetation, and bends' the same forward, bringingit comparatively closeto the ground, so that it cannotv come against the mould-board B, whichis thus enabled to turn the ysoil in 'a continuous and unbroken furrow,completely inverting the same, and of course burying underneath it thecornstalks, weeds, and like vegetation, thereby eiieotually securing theobject sought tobc attained by the invention.'

` What I claim as my invention, and desire to secure'by Letters Patent,is-ei 4 1. The sweep or bar C, attached to the beam A, and arranged inrelation with the nvloul'd-board D, leukste-ngA tially as and for thepurpose 'spece 2. The adjusting-links c d, and tightening-bolt f, incombnaton'with the sweep or bar C and the beam A, .substantially as andfor the purpose specified.

3. The chein or brace D, arrnged in relation with the sweep or bar C andthe beam A; substantally as and for the purpose specied.
